Problems solved by technology

With manual faucets, though users can select hot and cold water and control flow at desired rate, however, the flow cannot be closed after a certain time resulting in waste of water.

However, the conventional automatic faucets had some structural problems that the user could not choose between hot and cold water because the faucet didn't have the valve for controlling the amount of cold or hot water and therefore could not properly control the amount of the water.

Furthermore, the automatic faucet stopped working if the electronic parts didn't work in case of battery discharge or emergency.
